This research appraises how residential built environment growth influences coastal exposure and how this component of societal vulnerability contributes to tropical cyclone impact and disaster potential. Historical housing unit data and future demographic projections from a high-resolution, spatial allocation model illustrate that the area within 50 km of the US Atlantic and Gulf Coastlines ha...

The topic of tropical cyclone-ocean interaction has received increased attention in the tropical meteorology community over the past several years. It is widely recognized that the major energy source for tropical cyclones is the evaporation from the ocean. The sea surface temperature (SST) is a crucial parameter in this process. A negative feedback mechanism in the tropical cyclone-ocean syste...

We present results of a numerical study of the differential equation governing the stationary states of the two-dimensional planetary atmosphere and magnetized plasma (within the Charney Hasegawa Mima model). The results show an interesting similarity with the morphology of a tropical cyclone. Quantitative comparisons are also favorable and several scaling laws can be formulated connecting the ...

Trajectories of tropical cyclones may show large deviations from predicted tracks leading to uncertainty as to their landfall location for example. Prediction schemes usually render this uncertainty by showing track forecast cones representing the most probable region for the location of a cyclone during a period of time. By using the statistical properties of these deviations, we propose a sim...

A theoretical wind profile algorithm is implemented into a hurricane wind analysis tool to improve a 2-dimensional objective wind analysis. Validation of hurricane surface wind speeds from remote sensing technology has been difficult due to a lack of sufficient storm data needed for the National Oceanic and Atmospheric Administration Hurricane Research Division Real Time Hurricane Wind Analysis...

The preparation of a range of asymmetric iron and ruthenium-cyclone complexes, and their application to the asymmetric reduction of a ketone, are described. The enantioselectivity of ketone reduction is influenced by a single chiral centre in the catalyst, as well as by the planar chirality in the catalyst. This represents the first example of asymmetric ketone reduction using an iron cyclone c...

[1] Recent work has shown a statistical climatological link between African dust outbreaks and North Atlantic tropical cyclone frequency and intensity. However, a definite causal link between year-to-year changes in African dust and Atlantic tropical cyclones has yet to be proven. Here we show that variability in Atlantic dust cover is linked to changes in tropical cyclone activity through the ...

Atlantic basin increased markedly in the years 1995– 2000, compared with levels in the 1970s and 1980s. For example, the accumulated cyclone energy (ACE) index in the At lantic has been above the 1951–2000 median for all years from 1995 to 2005 except for the El Niño years of 1997 and 2002 (e.g., Bell et al. 2006). The increase in activity since the early 1980s has been confirmed using homogeni...
